It will output whatever the codec decides to output... we'll have to
check with different devices. But I would for now assume that it always
outputs byte-stream.

That's what existing code using MediaCodec suggests, yes.

Maybe it's not a direct array but a normal one. Has to be tried.

I don't know. Can you give the content of such a buffer? With
gst_util_dump_mem() for example.

That's a very good question :) I would guess that the in-stream codec
data buffers are a copy of the csd-X data. Has to be checked.
